35 Ferguson boasts a state-of-the-art air-conditioning
and ventilation system that incorporates highly
efficient air-cooled water chillers in the basement
and a rooftop package unit with a wraparound heat
coil supplying pre-treated outside air into the space.
The chiller plant comprises two air-cooled chilled
water generators (refrigerant R410A), generating
chilled water at 8°C. The chilled water is supplied
into the building with riser pipes where it branches
off at each of the five levels. After branching off, the
chilled water is supplied to ceiling mounted fan coil
units with electrical heater banks that is capable of
controlling the desired temperature with a tolerance
of 2°C up or down.
The roof of the building contains a rooftop
package unit with a wraparound heat coil supplying
pre-heated air in winter and pre-cooled air in
summer. The benefit of this unit is that no electrical
re-heater is required to sufficiently de-humidify and

re-heat the outside air. The process takes place with
no energy use due to the passive nature of the heat
pipe. The result is an air conditioning system that
sufficiently removes the moisture while using less
energy th an conventional de-humidification units.
The building features a high level Carel Building
Management System (BMS) composed of a
dedicated operator workstation including all the
necessary operating applications software and
applicable licenses to manage key building variables
as well as provide monitoring of key services at a
central point. The BMS monitors and manages and
provides alarm and warning notification of building
services in order to improve tenant comfort and
ensure building performance.
Electrical
Each floor’s electrical system was designed to be
completely flexible and on full back up power. UPS
infrastructure is scalable to the needs of the building.
